Roman Technology: Aqueducts

The engineering feats required to bring fresh water into Rome are astonishing, all the more so in light of recent revelations about the dangerous water systems in American cities like Flint, Michigan. Aqueducts offer another example of the strength and beauty of the Roman arch, supporting, with minimal construction materials, its structure far above the floor of a river valley. An aqueduct also brought water to the mill complex at Barbegal in southern France, powering a series of wheels for a variety of procedures. Clip from History Channel: "Engineering an Empire: Rome"
